I'm starting to think people post stuff like this just to get to the top of sites like HN. In this list I only see 2 items (Interview by E-mail and meet a potential employee's mate) that aren't common sense.
The rest boils down to Work Hard, Hire great people who get along, use Social Networking and Don't count your chickens before they've hatched. All advice that's been posted here 100,000 times in the past.
